Tech
Heating Circuit Manifold
Heating circuit manifold made of stainless steel for surface
heating and cooling systems with forced circulation. For
connecting two to twelve heating circuits to the heat or
cooling generator.
The heating circuit manifold consists of a flow distributor, a
return collector, wall brackets and fixing material. The
heating circuit manifolds are completely pre-assembled
with rotatable fill and drain cocks, vent plugs and end caps.
To simplify the installation of the heating circuit pipes, the
return collector (bottom) is moved forward in the wall
bracket.
The flow distributor is equipped with integrated flow rate
indicators. The return collector is equipped with QM valve
inserts with M 30 x 1.5 connection thread to connect
optional actuators. These are factory-fitted with a
protection cap, which can also be used to temporarily shut
off the heating circuit.
The heating circuit connections with G ¾ external thread
are suitable for Oventrop compression fittings. Sound
insulation according to DIN 4109.

Functions
Shutoff
HEATING CIRCUITS
Individual heating circuits can be shut off via the flow rate indicators. The QM presetting key enclosed with the heating circuit
manifold is used for this purpose.
In the return, the heating circuits can be briefly shut off with the supplied protection caps.
HEATING CIRCUIT MANIFOLD
For a complete shutoff of the heating circuit manifold to the system, ball valves must be placed between the manifold and the
system connection. These are not included in the scope of delivery. Suitable flat sealing ball valves for the manifolds are:
For the supply and return, red T-handle: item no. 1406383 (DN 20) and 1406384 (DN 25)
For the supply, red T-handle and thermometer: item no. 1406483 (DN 20) or 1406484 (DN 25)
For the return, blue T-handle and thermometer: item no. 1406583 (DN 20) or 1406584 (DN 25)
The different nominal sizes refer to the connection on the system side. The connection on the manifold side is always G 1,
matching the G 1 union nuts of the manifolds. See also chapter “Accessories“ further on.
Flow regulation with Q-Tech
Multidis SFQ heating circuit manifolds are equipped with QM valve inserts with Q-Tech technology. This
technology ensures that the flow through the heating circuit remains constant even with fluctuating
differential pressure.
The flow through the individual heating circuits must be throttled by means of the QM valve inserts in the
return to ensure hydronic balancing of the heating circuits connected to the manifold. The set values are
determined by a room-by-room heating load calculation, which can be carried out e.g. with the free OVplan
design programme.
Each heating circuit is set using the QM valve inserts. The setting range is 0.5 to 5 litres per minute (l/min). The set value can be
transmitted directly, as the scale on the valve insert is also given in l/min.
During setting, the circulation pump does not have to be in operation, actuators may already be installed, and the stroke
position of the actuators is irrelevant.
Flow rate check
During commissioning and operation, the flow rate of each heating circuit can be checked using the flow
rate indicators integrated in the flow distributor.
Important: The flow rate indicators only show whether the heating circuit is currently being flown
through or not. The position of the indicator does not provide any information about the water quantity.
